AR man ?

I've been following MGI since they have trying to produce there multi caliber AR the hydra... Basically this gun uses a modular receiver and can be be changed to any caliber including barrel swap in under 90 seconds using standard AR barrels. The gun can even go from AR mags to AK mags. Utilizing the same upper receiver and lower and converted in under 90 seconds. Any body ever tried one?
